Serum hemoglobin levels predict response to strontium-89 and rhenium-186-HEDP radionuclide treatment for painful osseous metastases in prostate cancer

OBJECTIVE: Retrospective comparative analysis of strontium-89 chloride (Sr89) and rhenium-186-hydroxyethylidene diphosphonate (Re186-HEDP) radionuclide treatment to find predictors of response in patients with painful metastases from hormone refractory prostate cancer. PATIENTS AND METHODS: Clinical data from 60 hormone refractory PCA patients (i.e. rising PSA at castrate testosterone serum levels) was obtained. Twenty-nine were treated with Sr89, 31 were treated with Re186-HEDP for painful osseous metastasis. Response was defined as a patient-reported decrease in pain and/or reduction in pain medication with stable pain level. Hematological parameters and serum levels of PSA, alkaline phosphatase, and lactate dehydrogenase were assessed prior to and at 4-week intervals after treatment. RESULTS: Median survival of all patients was 7 months (95% CI: 6-9 months). Overall, 33/60 (55%) patients reported a decrease in pain after the first radionuclide treatment. This percentage was similar for patients treated with Re168-HEDP and Sr89. Mean duration of reported pain response was 75 days (+/- 68 days) for Sr89 and 61 days (+/- 56 days) for Re186-HEDP, which was not significantly different. A lower blood hemoglobin concentration was associated with a lower pain response rate. In a multivariate Cox regression analysis, pain response to radionuclide treatment predicted longer survival after treatment. CONCLUSIONs: Pain response was present in 55% of patients. Serum hemoglobin concentration prior to radionuclide treatment predicted pain response for both Re186-HEDP and Sr89. A reduction in pain upon radionuclide treatment was associated with a longer survival after treatment.

Metastases to the penis from carcinoma of the prostate

A 58-year-old man presented with dysuria at the Osaka Medical College Hospital in November 1996. Laboratory examination revealed elevated serum prostate-specific antigen (PSA) to > 100 ng/mL. Adenocarcinoma of the prostate with metastasis to the bone was diagnosed after a biopsy of the prostate and bone scintigraphy; hormonal therapy was administered. Although bone metastasis was well controlled and the serum PSA level declined to within normal levels (2.0 ng/mL), several painless nodules were found on the penile glans. Biopsy of the nodules showed that the penile tumor was a metastasis from the prostate cancer. The patient underwent partial penectomy for relief from penile pain. The serum PSA level showed no elevation 3 months after the partial penectomy, suggesting that careful observation of prostate cancer patients is necessary, even when oseous metastasis is well controlled and serum PSA levels are kept within normal ranges by hormonal therapy. The case also indicates that urologists should consider the possibility of metastasis to the penis from prostate cancer.     

Multiple myeloma diagnosed during hormonal therapy for prostate cancer: report of two cases

Case 1: A 73-year-old man presented with a serum prostate specific antigen (PSA) level of 30.2 ng/ml, and was diagnosed with prostate cancer (cT3aN0M1, stageD2), for which hormonal therapy (maximal androgen blockade : MAB) was commenced. Nine months later he developed back pain, and osteolytic bone lesions progressed despite a stable, low PSA level (0.087 ng/ml). He was diagnosed with multiple myeloma on the basis of positive M protein on immunoelectrophoresis. MP combination therapy (melphalan and prednisolone) was commenced, but the patient died of multiple myeloma 33 months later. Case 2: A 70-year-old man was diagnosed with prostate cancer (PSA 19 ng/ml) at another hospital 5 years ago, and underwent hormonal therapy (luteinizing hormone-releasing hormone (LHRH) agonist only). He was referred to our hospital and underwent bicalutamide+MAB combination therapy due to a raised PSA level (58 ng/ml) and multiple bone metastases. His PSA level dropped to around 20 ng/ml, but 2 years later he developed back pain, and bone metastases with osteolytic change were seen in the skull, ribs, and limbs. Needle aspiration biopsy of a fist-sized soft tissue mass in the chest wall showed multiple myeloma. Although chemotherapy with melphalan was commenced, the patient died of multiple myeloma 8 months after its diagnosis. Both these cases exhibited rapidly progressing bone lesions, regardless of an absence of any large fluctuations in serum PSA levels, during hormonal therapy for prostate cancer. Further investigations yielded the diagnosis of multiple myeloma. If progression of bone lesions does not match the status of prostate cancer as surmised from the serum PSA level, we should consider the possibility of multiple myeloma, and biopsy of one of the bone lesions.     

Prospective evaluation of samarium-153-EDTMP radionuclide treatment for bone metastases in patients with hormone-refractory prostate cancer

PURPOSE: Bone is a common site of metastatic disease and the most frequent site of metastatic spread in patients with prostate cancer. Most patients with bone metastases complain of bone pains. This pain may be alleviated or eliminated by administration of radiotherapy at the site of metastases. Currently, two forms of radiotherapy administration exist: external-beam irradiation or intravenous administration of bone-seeking therapeutic radiopharmacon such as samarium-153-ethylene-diamino-tetramethylene-phosphonate (EDTMP). This radiopharmacon produces beta-particles and concentrates in the areas of enhanced osteoblastic activity. The aim of this study was to assess the efficacy of (153)Sm-EDTMP therapy. MATERIALS AND METHODS: 32 men (aged 50-83, mean 70 years) with bone disseminated hormone-refractory prostate cancer and bone pain received (153)Sm-EDTMP. Mean applied dosage was 40 MBq/kg of the patient's body weight. Karnofsky performance status, pain score (numerical rating scale), analgesic score (WHO) and blood count were evaluated before, and 1 and 3 months after the treatment. RESULTS: Significant pain relief was observed in 44 and 38% of patients, mild relief in 31 and 34% and no effect in 25 and 28% of patients, 1 and 3 months after administration, respectively. Pain palliation was accompanied by an improvement in mobility and a decrease in necessary dosage of analgesics. Mild and transient bone marrow suppression was observed as a side effect of (153)Sm-EDTMP treatment. None of the patients showed hematological toxicity grade 4, and only 2 showed grade 3 (NCI CTC). The majority of the patients had hematological toxicity grade 1 or 2. CONCLUSION: After (153)Sm-EDTMP administration, bone pain palliation was observed in 72% of patients for 3 months. Hematological toxicity after (153)Sm-EDTMP treatment was mild and transient.
